Composition for improving wettability of surfaces

摘要

The invention is directed to a method for improving the wettability/hydrophilicity of hydrophobic substrates by applying block copolymers to said substrates wherein the block copolymers comprise a quaternary ammonium polymer block and a hydrophobic block. The method of the invention is especially advantageous when used to improve the wettability of non-wovens and in the treatment of hydrophobic surfaces encountered in the home to prevent the buildup of soil residues.
